Isabel Symptom Checker - What makes it so different?

  • The Isabel SC uses the medically validated Isabel DPREP system. Unlike most other symptom checkers it enables patients to enter multiple symptoms in everyday language and helps make sense of them. The combination of symptoms is analysed by the Isabel artificial intelligence engine and possible conditions are linked to further knowledge so the patient can research their symptoms. A ‘Where now?’ (triage) feature is also provided to help patients decide where to seek care within your health system.


Isabel SC is simple to use…

Easy entry of multiple symptoms in everyday language, combined with patient’s age, gender and region. The region can be changed to highlight potential diseases related to recent travel history.


returning relevant conditions…

The list can be sorted by different views, highlighting common and red flag conditions. Each condition links through to patient-friendly disease information.


generating greater patient engagement…

The versatility of Isabel SC enables it to be incorporated in a wide variety of workflows and contact points within your health system (e.g., built into your public facing website, patient portal or personal health record, e-visit, workflow etc.) improving efficiency and the patient experience.

…and connecting patients to the appropriate care setting within your health system

After answering key questions about their symptoms, a unique set of algorithms consolidates the information entered and recommends the most clinically appropriate setting to seek care within your health system.



"On average, symptom checkers provided the correct diagnosis within the first 20 listed in 58% of standardized patient evaluations, with the best performing symptom checker (Isabel) listing the correct diagnosis in 84% of standardized patient evaluations."

Driving patient engagement

Isabel enables patients to be partners in their care and work as a team with their health professionals. Health systems are encouraging patients to use the Isabel SC via their patient portals prior to their visit to drive quality engagement and efficiency.
